The record

Product: nono describes itself as agent runtime security with kernel-enforced boundaries for AI agents.
Execution isolation: It creates ephemeral, invocation-scoped micro sandboxes for tool calls, with scoped files, network routes, arguments, and credentials.
Kernel enforcement: The OS sandbox uses Landlock on Linux and Windows/WSL2 and Seatbelt on macOS; the page says no root is required.
Agent compatibility: The site lists Claude Code, OpenCode, Codex, Antigravity, Goose, OpenClaw, GitHub Copilot, Qwen Code, Pi, and Hermes.
Policy profiles: JSON profiles define agent access and can be version-controlled alongside code.
Rollback: SHA-256 content-addressed snapshots record filesystem state before and after sessions, and the page describes restoring a session atomically.
Audit: The audit trail records operations in a Merkle tree and commits a SHA-256 root at session end for integrity verification.
Credential handling: The site says credentials are injected at the boundary and never exposed to the agent.
Network control: The homepage describes proxy-mediated network access where policy can allow or deny requests and route out-of-policy actions for human approval.
Developer interfaces: The documentation lists a CLI, a Rust core library, and Go, TypeScript, and Python SDKs.
Installation: The homepage offers a shell installer, Homebrew, and links to Debian, Fedora, Arch, and Nix installation instructions.
Windows caveat: On WSL2, the page reports 84% feature parity and says capability elevation and per-port network rules have limitations.
Support: The documentation links to Discord for community support.
